1.DHCP 实例配置## 配置步骤(在路由器上配置)
### (1) # 配置接口的 IP 地址。
<H3C> system-view
[H3C] interface g 0/0
[[H3C-GigabitEthernet0/0]] ip address 192.168.1.254 24
[[H3C-GigabitEthernet0/0]] quit
### (2)# 启用 DHCP 服务。
[H3C] dhcp enable
### (3) # 配置不参与自动分配的 IP 地址。
[H3C] dhcp server forbidden-ip 192.168.1.10
[H3C] dhcp server forbidden-ip 192.168.1.254
(4)# 配置 DHCP 地址池 0,采用动态绑定方式分配 IP 地址。
可分配的网段为 192.168.1.0/24,租约有效期限为 10 天,DNS 服务器地址为 192.168.1.10。
[H3C] dhcp server ip-pool 0
[H3C-dhcp-pool-0] network 192.168.1.0 mask 255.255.255.0
[H3C-dhcp-pool-0] expired day 10
[H3C-dhcp-pool-0] dns-list 192.168.1.10
[H3C-dhcp-pool-0] gateway-list 192.168.1.254
[H3C-dhcp-pool-0] quit
DHCP服务器在路由器上,而SWA上有3个VLAN,分属于3个不同网段,
DHCP的请求报文是广播,因此必须在SWA上设置中继才能够传到路由器。
